Extend_HLF_testnetwork

This repository demonstrates the setup and expansion of Hyperledger Fabric test networks with varying organizational structures. The network configurations include:

Organization Structures: Configurations:

• 4 peers in Organization 1, 1 peer in Organization 2
• 4 peers in Organization 1, 4 peers in Organization 2
• 8 peers in Organization 1, 1 peer in Organization 2
• 8 peers in Organization 1, 4 peers in Organization 2
• 8 peers in Organization 1, 8 peers in Organization 2

Branches:

• master branch: Sets up and configures these networks.

• setupFabcar branch: Installs Fabcar chaincode across each network configuration and conducts performance tests using caliper-benchmarks.

• setupDrug branch: Similar to setupFabcar, but employs chaincode tailored for drug supply chain management that we coded.

• Each branch provides a specific setup and testing environment for different chaincodes, facilitating performance evaluation and use-case exploration within distinct network structures.

Installing Hyperledger Fabric test-network

• Install test-network

Step 1: Installing Hyperledger Fabric version 2.2.1

To install the test-network, you can follow the instructions in the Hyperledger Fabric documentation or execute the following commands:

curl -sSLO https://raw.githubusercontent.com/hyperledger/fabric/main/scripts/install-fabric.sh && chmod +x install-fabric.sh
./install-fabric.sh --fabric-version 2.2.1 docker samples binary

Follow the step-by-step instructions detailed in this link to confirm the proper functionality of the test-network.

Extend test-network

• clone this repository

step 3: go to the location where the fabric-sample directory is located. For example, if the address of the fabric-sample directory is ""/home/file1/fabric-sample"", go to ""/home/file1"", then clone the master branch of this repository.

step 4: In the "Extend_HLF_testnetwork" folder repository, open a terminal and run the following command:

./mergefiles.sh

step 5: Execute the desired setup_?_?.sh script(s) in the ""fabric-sample/test-network"" directory using the following command format:

./setup_?_?.sh

Replace '?' with the desired script identifier to proceed.
